應用

通用 Western 印迹法方案:
  • 糖蛋白样本量:500 ng
  • 凝集素浓度:0.1 μg/mL

  1. 每个泳道加入500 ng糖蛋白样品
  2. 运行 4-20%Bis-Tris SDS 页面凝胶
  3. 将凝胶转移至 PVDF 膜上
  4. 用 RTA 缓冲液(R0278 Sigma)在室温下封闭膜 1 小时
  5. 在室温下用 RIPA 缓冲液将 HRP 凝集素以 0.1ug / ml 孵育 2 小时
  6. 用 25ml RIPA 缓冲液洗涤膜 5×5 分钟
  7. 使用化学发光底物(CPS1-120)进行检测

生化/生理作用

花生凝集素不会凝集正常的人类红细胞,但会强烈凝集神经氨酸酶处理的红细胞。花生凝集素具有与人血清中的抗 T 抗体相似的有效抗 T 活性。凝集素可用于区分人淋巴细胞亚群。

單位定義

在 20°C、pH 值为 6.0 条件下,1 个单位的邻苯三酚在 20 s 内会形成 1 mg 红桔酚。

外觀

含柠檬酸钠

準備報告

采用改进的已发表方法,通过过氧化物酶 (P8375) 制备,有利于低分子量偶联物。通过亲和层析缀合后再纯化。

Protein O-glycosylation has key roles in many biological processes, but the repertoire of O-glycans synthesized by cells is difficult to determine. Here we describe an approach termed Cellular O-Glycome Reporter/Amplification (CORA), a sensitive method used to amplify and profile mucin-type

A non-replicating form of pseudotyped influenza virus, inactivated by suppression of the haemagglutinin signal sequence (S-FLU), can act as a broadly protective vaccine. S-FLU can infect for a single round only, and induces heterotypic protection predominantly through activation of cross-reactive

Dicer is a crucial enzyme for the maturation of miRNAs. Mutations in the Dicer gene are highly associated with Pleuro Pulmonary Blastoma-Family Dysplasia Syndrome (PPB-FDS, OMIM 601200), recently proposed to be renamed Dicer syndrome. Aside from the pulmonary phenotype (blastoma)

Virus-like particle (VLP) technology is an alternative platform for developing vaccines to combat seasonal and pandemic influenza. Influenza VLPs are non-infectious nanoparticles that can elicit effective vaccine immunogenicity in hosts. B-cell-activating factor (BAFF, or BLyS) and a proliferation-inducing ligand (APRIL)

Ectothermal reptiles have internal pigmentation, which is not seen in endothermal birds and mammals. Here we show that the development of the dorsal neural tube-derived melanoblasts in turtle Trachemys scripta is regulated by similar mechanisms as in other amniotes, but
